for breakpoint and trace traps from usermode. Although all the setidt
entries are interrupt gates on amd64, all but the trace and bpt trap
entry handlers reenable interrupts after the swapgs instruction in order
to simulate the trap/interrupt gate distinction. In other words, the
amd64 code behaves the same way that i386 does here.
for ddb input in some atkbd-based console drivers. ddb must not use any
normal locks but DELAY() normally calls getit() which needs clock_lock.
This also removes the need for recursion on clock_lock.
known constants at compile time rather than at run time. We have a number
of nasty hacks around the place to cache ntohl() of constants (eg: nfs).
This change allows the compiler to compile-time evaluate ntohl(1) as
0x01000000 rather than having to emit assembler code to do it. This
has other smaller flow-on effects because the compiler can see that
ntohl(constant) itself has a constant value now and can propagate the
compile time evaluation.

Also in _thr_sig_handler, retrieve current signal mask from kernel not
from ucp, the later is pre-unioned mask, not current signal mask.

- Increase the granularity of the vm object locking in vm_hold_load_pages()

same lock.
Fix to the messages output under CAM_DEBUG_CCB: the summary sense
information (error bits and sense key) is in the error field, not
in the result field, of struct ata_request. No other functional change.
completion of recovery is indicated by positioning the CAM_AUTOSNS_VALID

This fixes an endless loop of sense recovery actions.

function, startup_alloc(), that is used for single page allocations prior
to the VM starting up. If it is used after the VM startups up, it
replaces the zone's allocf pointer with either page_alloc() or
uma_small_alloc() where appropriate.

Tested by: phk/amd64, me/x86
Temporarily disable the UMA_MD_SMALL_ALLOC stuff since recent commits
break sparc64, amd64, ia64 and alpha. It appears only i386 and maybe
powerpc were not broken.
